Repair, don’t replace that broken pinball coil!

Pinball coils (aka solenoids) are windings of insulated copper wire that create electromagnets that make things move on the playfield. If you have a coil that is no longer working, and doesn’t have any obvious signs it has “melted down”, there’s a very good chance you can repair it instead of replacing it. In this video I go over how this is typically done. This works on all types of pinball machines from the EMs to Stern, Bally, Williams, etc.

Fabricating a new lane guide for a Flash Gordon, reinforcing with metal and touch-up painting and protecting

In this installment, I’m working on a Flash Gordon pinball machine. There’s a common plastic part that breaks that is very difficult or expensive to replace. I go over how to replace this part by fabricating your own plastic lane guide using common parts from local hardware stores.

In Part 2, I take things a step further by adding a metal reinforcement plate to keep the guide from breaking in the future, and I show off some amazing playfield paint touch up work and use lacquer to seal the touch-ups:

Recommended mods to Bally-18/35 and Stern solenoid driver boards

In today’s episode, I go over some standard, recommended modifications to the Bally-35 series solenoid driver board. There are over 60 popular pinball games that use this hardware setup and these quick modifications will help make the game run better and more-reliably. They involve adding three jumpers to the board. Whenever I have a chance to work on one of these boards, I do these mods.

Here are some front and back pictures of both Bally and Stern Solenoid driver boards. The black wires are the mods. The other colored wires are done by operators having to do with the coil lockout relay.
